Attic Fan Cyclone Solar Powered (Turbine Mount)
Cat. No. SDF-20TM
Weight 15 lbs

SDF-20TM (Turbine Mount) is a unit designed to fit the base assembly of any 12” wind turbine. Ease of installation is of course the great benefit of this product, utilizing an existing penetration into the home without disrupting the existing seal.

Good sun exposure, preferably a south-southwest afternoon exposure for optimum fan operation, but because the PV Panel orientation is horizontal in this installation it is not 100% necessary. What is essential is proper elevation of the fan in relation to the ridgeline of the home (see diagram). If the PV panel is allowed to fall into the shadow under the ridgeline it can hinder generating power, at the precise time we’d like to see it operating at it’s strongest

Turbine Mount Installations:

The primary reasons to buy this product are: ease of installation, less concern with H.O.A.’s and of course decreasing the potential problems involved with putting a new hole in the roof. Our Turbine Retrofit will allow us to use any existing hole if that’s what the customer prefers. Our PV Panel is bedded in Tempered safety glass, making it one of the most efficient panels in the world when it comes to light sensitivity. It’s horizontal orientation will insure a very positive performance of the fan through out the whole day PROVIDED it’s not asked to operate out of the shadows as shown in Fig A, . Figure B. shows the PV Panel slightly elevated above the ridgeline. This installation will allow for optimum performance by the fan.

Benefits of a Solar Powered Super Cyclone
All attic ventilators, powered or solar vent out the hot air built up within the attic, but a solar unit offers additional benefits not possible with a powered product. Because a Solar Dynamics PAV turns on at dawn, it goes to work immediately, first to eliminate the moisture that has built up from the cool overnight air, and second, to prevent heat build up before it has a chance to build up to the point of convection. A standard PAV has to reach a high temperature before the thermostat kicks in and tells it to start working. By this time the moisture has already worked its way into the insulation and the walls, doing its damage. Because it has to play “catch-up” the PAV is already starting out at a disadvantage and must run all day. Driven off AC power, a PAV can be noisy emitting “harmonic noise”, and although it is possible to override the thermostat and let it run, the motor is not designed to handle this constant demand.
